As a general contractor in Madison, Wisconsin, National Construction’s goal is to partner with local business owners to drive economic growth. The name National Construction describes the community focus of our building experience, and our vision to partner with business owners and architects across the nation. We’re passionate about hometown life in Wisconsin and beyond. We’re loyal to the community ideal, and we’re devoted to keeping the communities we work in strong.

Neil Johnson founded the commercial construction company in 1990. He later partnered with JG Development, headquartered in southwestern Wisconsin and owned by Jeff Grundahl and Mary Grundahl, on some larger projects. In 2008, Neil sold the firm to JG Development and moved into a superintendent role – a position he holds today.

We are one of four divisions of JG Development, with offices in Blue Mounds and downtown Madison, Wisconsin. Among Madison builders, National Construction maintains an ideal balance of low overhead and high capacity, so you can be sure your funds will be applied efficiently for the best result. We offer several building design and construction options, whether your project is a small remodel or a multi-million dollar community improvement initiative.

And while we believe the best outcomes come from collaboration early in the process, National Construction can be trusted to deliver quality within the process that best fits your timeline and resources.

To National Construction, your project is the priority of your dedicated team. Contact us today.
